test: migrate Fam10 alias value tests to @test, carve divergences to pins (#5-C3)

fold-2 chunk C3 (drew's Fam8-13 plan): 8 alias value-row C drivers, 205 rows
re-homed with zero loss -- 177 value -> 8 test/lang/alias_*_test.ww @test
row-tables; 16 reject -> runww //ww:error carriers (both stages reject);
3 cs!=ww value rows -> 2 *_runonly_test.ww (T1, byte-id-excluded, #60/#81);
9 irreducible asymmetric rows -> slim C pins, each ticket-cited and
mutation-proven non-vacuous:
  - accept amplen1/2,ampcap2: cs runs / ww rejects 'unsupported address-of
    shape' (#96)
  - cgen_b5 g73_heapfill: cs!=ww .s + ww link-fails on self-contained alloc;
    compile-smoke pin (#24)
  - cgen_b6 fsarg2_bound: both reject, different msgs, each vs the correct
    stage (#271/#165 cs vs #272/#276/#277 ww)
  - emit_b7 slc/slcstr/slctag _2lvl + slc_plain_ctl: slice-literal static-init
    divergence (#120/#29-kin, ken-d2-oracle)
4 fully-migrated drivers deleted, 4 slimmed-in-place to hold only the
irreducible pins. LANGBYTEID floor 74->82 (8 new byte-id @test files); test
count 388->384 (4 deleted; 4 slimmed kept). do-not-auto-batch files not in
Fam10.
